Balloon catheter with stent securement means
First Claim
1. An assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising:
- a catheter having proximal and distal ends and an inner shaft;
an expandable balloon coaxially mounted on the catheter axially; and
a tube component coaxially mounted on the catheter axially within the expandable balloon.

Abstract
An assembly for delivery and deployment of an inflation expandable stent within a vessel is comprised of a catheter, an inflation expandable stent, an expandable balloon, and a securement means such as a corrugated tube component or an expandable tube component. The tube component is mounted on the inner shaft beneath the balloon and provides increased securement to the stent in a reduced delivery diameter to maintain the stent on the catheter during delivery to the deployment site. The tube component is adhered to the inner shaft and has a plurality of ribs or is fluid expandable to no more than the delivery diameter. and may be comprised of more than one separately inflatable pouch expandable to provide the stent with a substrate seat with increased friction and to decrease the slack in stent recoil crimping. The assembly is used in a method for delivering and deploying a stent, and also adds safety when loading/crimping the stent onto a balloon.

26. An assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising:
-
a catheter having proximal and distal ends and an inner shaft;
a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end;
an expandable balloon coaxially mounted on the catheter axially; and
a securement means for securing the stent to the balloon, the securement means coaxially mounted on the catheter axially within the expandable balloon.
